Hello again!

You can download the project files here:


Once you open up the project in VWD 2010, open the default.aspx file.

Run the program.

Visually, there is not much to this. The bulk of the work is in getting a web service set up. I just created the default.aspx to show the web service working.

The web service is actually in uniqueid.asmx

Default.aspx consume the web service and displays the results. As you can see, it displays a unique identifier. If you reload the page, there will be a new unique identifier.

The web service take your IP address and the current date/time. I concatenates this information and then performs and MD5 hash on it. This results in a unique identifier based on the IP address, date, and time.

Let me know if you have any questions. I'm here to help.

Please remember to rate my answer. It is greatly appreciated. Thank you so much and have a wonderful day!

This looks great to me. I'll see what my teammates think and let you know if I have questions. When I submit the completed web application, I will zip the database, profile info app, and unique identifier app for the final.
